New Delhi: Dengue fever is a painful, debilitating mosquito-borne disease caused by dengue viruses. Each year, an estimated 400 million people globally are infected with the virus; about 100 million get progressively sick and 2.5 percent of those patients die. It is the fastest growing mosquito borne infection in the world.

The World health Organisation (WHO) estimates that 40 percent of world's population is at risk of being infected due to environmental conditions and burden of disease; people of all age groups are at risk. Most people who are infected have mild or no symptoms.

Dr Mohammed Sakeel of Fortis Hospital, Kalyan, said that mild symptoms of dengue may be confused with other illnesses that cause fever and flu-like symptoms. He stated that the most common symptoms are fever, and one or more of the following:

Severe symptoms of dengue can be labelled as an emergency. Therefore, it is important to recognise the warning signs early.

Warning signs:

Watch for signs and symptoms of severe dengue, which develop 24-48 hours after initial fever goes away. If you or a family member develops any of these warning signs, go to a physician or nearest emergency department immediately:

According to Rasika Parab of Fortis Hospital, Mulund and Rajeshwari Shetty of SL Raheja Hospital, dengue has the most vague myths associated with itself and the rise of social media just adds to the problem.

"We try to look up our symptoms and make a guess about our diagnosis; we also receive plethora of information on social networking and messaging platforms, some true and some untrue. Believing and following every piece of information received on networking platforms, and otherwise, is not a wise thing to do," they said.

Therefore, if you have symptoms of dengue, rather than following the advice on social media, consult your doctor immediately. To reduce the mosquito population, get rid of places where mosquitoes can breed - these include old tires, cans, or flower pots that collect rainwater. Stay wise and keep your surroundings clean.
